実験手順

250 mg of benzyl{[[2-(o-fluorobenzyl)-4-[3-(2-acetoxyethyl)ureido]phenyl]methylcarbamoyl]methyl}carbamate dissolved in 10 ml of absolute methanol are treated with 50 mg of sodium methylate, stirred at room temperature for 1 hour and buffered with a small amount of acetic acid. The mixture is poured on to ice/10% sodium bicarbonate and extracted with methylene chloride. The organic solution is dried over sodium sulphate, filtered and concentrated. After crystallisation from ether/ethanol, there is obtained benzyl{[[2-(o-fluorobenzoyl)-4-[3-(2-hydroxyethyl)ureido]phenyl]methylcarbamoyl]methyl}carbamate which melts at 117°-120° C.
